In a large bowl, combine the minced shallot, minced garlic, red wine vinegar, fresh lemon juice, lemon zest, Dijon mustard, salt, black pepper, and chile flakes. Whisk everything together until the salt dissolves and the mustard is fully incorporated. Let this mixture sit for 2-3 minutes—this allows the shallot and garlic to soften slightly and release their flavors into the acidic base, creating a more mellow, integrated vinaigrette. I like to use freshly squeezed lemon juice here because the acidity level is more pronounced and the vinaigrette will stay fresher longer.

Slowly drizzle in the olive oil while whisking constantly. This gradual incorporation helps create a stable emulsion—the mustard acts as an emulsifier, helping the oil and acidic components stay suspended rather than separating. Whisk until the vinaigrette becomes silky and slightly thickened. I prefer California Olive Ranch oil for its peppery finish, which adds nice complexity to the final salad.

Add the rinsed and drained white beans directly to the bowl with the vinaigrette, along with the chopped parsley and chives. Gently toss everything together, making sure the beans are evenly coated with the dressing. The warm acidity of the vinaigrette will season the beans thoroughly while the fresh herbs brighten the overall flavor.

Gently fold in the crumbled feta cheese, being careful not to break it into tiny pieces—the larger chunks provide pockets of creamy, salty texture that contrast beautifully with the lemony beans. Taste and adjust seasoning if needed. Serve immediately or at room temperature, as this salad tastes best when the components are fresh and the flavors haven't muddied together.
